The sign, which appeared to be professionally produced, also included a crying emoji to nail home the father’s point. The unidentified dad’s sign surely turned some heads, making it onto ESPN and the Instagram account of sports photographer Jeremy Brevard, who posted it along with the caption: “Tough love.”

The trolling father was also roundly praised on social media, particularly on Twitter, where he was called “dad of the year” and “hilariously ruthless,” among other pleasantries.
